Holden 253-308 V8 1 5/8in Header Flange Non EFI Head for selected vehicle applications.
Category: Extractors and headers


The MPI Automotive MHF5210 is a header flange for the Holden 253 and 308 V8, cut for 1⅝in primary tubing and machined to the non-EFI head pattern. Two things define it: the small-bore 1⅝in primaries and the non-EFI head profile it's matched to — the carburettor-era head, not the later injected layout.
The MHF5210 is profiled for the non-EFI Holden V8 head — the earlier, carburettor-era casting. Head pattern is what makes or breaks a flange: the bolt holes and port spacing have to land on your head exactly. Getting the non-EFI version means it's matched to that specific layout rather than the later injected head, so confirm which head your 253 or 308 wears before ordering.
The flange is cut for 1⅝in primaries, the smaller of the common bores. Smaller primaries keep exhaust gas speed up, which favours low-down and mid-range response — well suited to a street Holden V8. As a flange it's the head-side foundation a fabricator builds the header from, not a finished bolt-on.
It's the plate that bolts to the cylinder head and locates the primary tubes during fabrication. The MHF5210 is a build and repair component for the 253/308 V8 — you weld 1⅝in primaries to it to construct or repair a set of headers.
Oak Flats Muffler Men supplies this MPI flange and can fabricate or repair the headers around it. Bring your Holden V8's head details — confirming it's the non-EFI head — and we'll check the 1⅝in flange suits the build before ordering.
